TERMINAL STRIP.

Specification of Letters Patent.

Patented May 1,1906.

Appli ti fil d, November 9, 1.904. Serial No. 231.981-

To all whom it may concern.-

Be it known that I, HAnRY J. GUTTMAN, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State .of Illinois, have invented a certain new and useful Improvement in Terminal Strips, of which the following is a specification.

My invention relates to the arrangement of metallic electric terminals in banks or strips.

Generally stated, the object of my invention is the provislon of an improved and highly efficient form of terminal strip, and a special object is to provide a strip of terminals' of such construction. that it may be economically manufactured and satisfactorily employed in completing the circuits or connecting up the wiring of any kind of electric apparatus, and it is also an object, of course, to provide certain details or features of improvement tending to increase the general efficiency and serviceability of a device of this particular character.

To the foregoing and other useful ends my invention consists in the matters hereinafter set forth and claimed.

In the accompanying drawings, Fi ure 1 is a perspective of a terminal strip em bodymg the principles of my invention. Fig. 2 is a perspective of one of the metal terminals before it is applied to the strip of insulation. Fig. 3 is a perspective of one of the metal terminals bent into shape to be applied to the said strip of insulation. tive of a portion of the strip of insulation before the metal terminals are applied.- Fig. 5 an enlarged. cross-section of the terminal strip. Fig. 6 is an edge view of several of the terminal strips arran ed one above the other in the form of a ban and secured together and separated from each other. by means of a screw and washers.

As thus illustrated, my invention comprises a plate or strip of insulationA of any suitable size or dimensions. Preferably the said late or strip of insulation is provided with olt-holes a and also with openin s (If-for the metal terminals. When stamped out of sheet metal, the said metal terminals. B are each of the character shown in 2. These terminals are, however, then bent into the shape shown in Fig.- 3.- After this each terminal is inserted downwardly through a pair of the openings a, so as to extend crosswise Fig. 41s a perspec- Finall the Figs. 1 and 5.) In this way each metal terminal when applied to the strip of insulas tion has its end portions .restm flatwise against one surface of the said strip of insulation and its middle or intermediate portion held fiatwise upon the other side or surface of said strip of insulation. Consequentl each metal terminal when inserted and ad justed in place has lengthwise end and intermediate portions 1), b, and b, which are connected at their ends by short crosswise -7 or transverse portions b and b. It will be seen that these portions b and I) extend through the openings 0' and are substantially of the same length as the latter. With this arran ement each metal terminal is held very secure yin placewithout the aid of anyfastening devices.

As shown in Fig. 6, several strips of the character shown inFig. 1 are arranged one,

above the other, with lenty space between and are held togethery means of a screw 0 and separated one from the other by means of washers 0. With this construction it is evident that any desired number of the said terminal strips may be secured together to form a bank of metallic terminals or electric contacts or other like devices of any desired size or ca acity.

What claim as my invention is 1. A strip openings, and a plurality of metal strips extending crosswise .of said strip of insulation, each. metal strip having end portions lying fiatwise upon one surface of said stri of insuof insulation provided with lation, and having also an interme iate portion lying flatwise against the opposite surface of said strip of insulation the said metal strips being suitablyspaced apart andinsulated from each other and provided with free ends adapted for connection with circuit-contoo 2. A strip of insulation provided with parallel rows-ofopenings, and metal strips applied to said openings and extending crosswise of said stri strip having en and intermediate lengthwise portions lying flatwise against the opposite surfaces of said strip of insulation, and

of insulation, each metal m metal stri being I. ing beyond the opposite edg Correction in Le tters Patent No.'819, 060.

having also relatively short crosswise or transverse portions exten throu h sa d openings in the strip of ation e said suitably spaced a art andinsulated 0m each other and provi ed with fi'ee ends adapted for connection with circuitconductors;

3. A strip of insulation rowded w1th parallel rows of openings, an parallel stnps of metal inserted through said openings and extending crosswise of said strip of msulatmn, each metal strip having end portions pro ectes of said strip of insulation, and having an intermediate portion-joined to said verse portions which openings, whereby the end and intermediate rtions of said metal strip are held flatwise against c urfaces of the strip of inoaposite s D O sulation c said metal strips be ng suitably spaced ap art and insulated from each other and rovlded with free ends adapted for connection with circuit-conductors.

4. A strip of insulation firovided with o enings, and U-shaped met strips inserted through said openings and havin their end portions bent outwardly to prov'i e electric or contacts, each of said mem- .bers havin its end portions segzrated from its middle portion by the thic ess of said extend through said [emu] end portions by trans-- strip of men lation whereby the said mi dle portions are disposed upon or at o posite y-facing surfaces of t e said metal strips being-suitably 'sgaced apart and insulatedfrom each other an provided with free ends adapted for'connection with circuit-conductors. 4

5. Abank of electric terminals or contacts,

the

' com rising a plurality of flat'filrates of insulation eld together by screw-t eaded means, and separated one from the other by washers mounted upon the said screw-threaded means, each plate of insulationbeing provided with a pluralit tacts, an each electric terminalor contact consistin ofastri ofmetalhavingprojecting end portions hel fiatwise agfiinst one surface of its allotted plate, and. aving also an intermediate portion held flatwise a 'ainst the opposite surface of such plate th said meta stri 8 being suitably spaced agaitand insulated min each other and provi ed with free ends adapted for connection with circuitconductors.
